Underscore.js is a JavaScript library which provides utility functions for common programming tasks. It is comparable to features provided by Prototype.js and the Ruby language, but opts for a functional programming design instead of extending object prototypes.
These statistics include detections outside the stricter public preview. Counts can exceed the qualifying domains above; they describe our coverage, not internet-wide market share.
Search databaseUnderscore.js is a javascript framework technology. Underscore.js is a JavaScript library which provides utility functions for common programming tasks. It is comparable to features provided by Prototype.js and the Ruby language, but opts for a functional programming design instead of extending object prototypes.. Currently detected on 9,436 quality-eligible websites in the Glympt index.
Official website: underscorejs.org.
Includes observations below the public country preview’s confidence and quality thresholds. These are website geography signals, not verified business locations.
Counts include broader stored detections, without the public preview’s quality filters. Co-detection describes an observation, not a recommendation or integration guarantee.
By scanning headers, HTML, JS globals, meta tags, and cookies. Detection is automated and non-intrusive.
The average detector score for Underscore.js is 98/100. It measures matching evidence, not independently verified accuracy.
Yes. Pro and Business plans include CSV export with full filtering.
Observation dates are shown on each report. Refresh timing varies with crawler capacity; you can request a fresh scan from the dashboard.
Our database recorded a net change of 44 observations in 30 days. New coverage and rescans affect this number; it is not a measure of market growth or migrations.
A 0–100 detector score based on matching signals. Stronger evidence increases the score, but false positives and missed technologies remain possible.
